ALBERT C. RosENcaANz,'oF EvANsvILLE,l INDIANA AssiGNoa To THE vULoAN PLOW COMPANY; A CORPORATION OFvv INDIANA.

l'To all 'whom it may cuoltcern':` I Be it knownl that I, ALBERT C. ROSEN- cnaNz, a citizen'of the United States, residing at Evansvillein the county oi' Vanderburg and State of Indiana, .have invented certain new and useful Improvements 1n llows; and I do hereby declare the followplows, and particularlyto improvements in fastening points on a sub-soil plow/,and has tor an obJect the construction4 of a plow with a strong point that Amay be readily and quickly removedl and againv replaced, together with means for holding the point in position that will not readily getout of order. l i.

A further object of the invention is the lproduction or' a plotsT having a strong and rigid standard with a removable point held Ain place by a single securing means.

With these and other objects in View, the invention comprises certain novel construetions, combinations, and arrangements of parts as Will `be hereinaftermore fully described and claimed.

In thel drawings: Figure 1 is a side velevation of a plow embodying the present invention. Fig. 2 is an enlarged, detail, longi. tudinal, vertical section through the standard and point;` Fig. 3 is a bottom plan vieW of the structure shown in Fig. 2. Fig. 4' is a section through Fig. 2 on line 1 -4f.y Fig. 5 is a top plan view of the point securing means removed. Fig. 6 is a top planof the point removed. Y

In the construction of a plow embodying the features of this invention, a beam of any kind is used and handles of 'any kind may be used having connected. therewith a standard to which is secured a removable point which is slipped over the point or nose of the standard and isheld in positionl by a hook-shaped projection on a landside bar engaging the same. 'lhe landside bar in turn is held in position, preferably by a single bolt, so that the point may be said to be held in place byy a single securing means, as the moment the bolt is removed the point and the landside that engages kthe saine can be disengaged from the standard.

ln order that the invention may be more specification o'f Levtterrsratent'. Application filed January 15, 1909.

l a reduced .of the base. The reduced point 4 is designed Patented June s, 1909.

Serial-No. 472,469.

clearly understood, an embodiment of the saine is shown in the accdmpanying drawings, inI whichl indicates the beam and 2 handles.' To the beam l-andthe handles 2 the standard l3, preferably oione piece, is connected. The standard 3 is formed with the guiding i a reduced point l having an offset 5 and also portion 6 extending longitudinally to lit into a removable point 7 which point engages the shoulderv portion 5 and forms a continuous surface from the extreme point of point 7 to the standard 3. The point 'T is formed substantially hollow, as more clearly 'seen in Fig. 6, and is formed with. a cross baror member 8 over which a hook 9 lis adapted to pass when assembling the point upon. the standard 3. The hook 9 extends fromflandside 10 and is preferably formed integral therewith, as shown in Fig. 2. Landside 10 is formed with flanges 11 and l2 that partially encircle the reduced portion 6 of standard 3, and by such encircling the -la'ndside bar is guided in its reciprocatory` movement when `pulling point 7 into osition. The l'andside 10 is also formed with a projecting lug 13 `that has passing therethrough an opening for receiving a bolt 14., Bolt l-l also passes through a lug or eXtension 15 of standard 3, and the lug or extension 13 operates or reciprocates in a hollowed-out portion 16 of standard 3.

In assembling the device, all that is necesf sary is to slip the point A7 on the nose orl point 4 of the standard, and then insert the hook 9 in the landside bar'lO. The hook 9 Will vpartially encircle cross-bar 8 .and the sides l1 and 12 will engage the reduced portion 6 and thereby form'mea'ns by which the bar is guided in its movement. The point 7 is forced as far as possible on the reduced point t, andlandside bar 10 ismoved backward from the point as far as` possible and then the bolt 14C inserted. The bolt after insertion is turned until the point is securely in position on the standard.

What l claim is:

l. .ln a plow, a standard, a removable point, a landside having a hook onone end, said hook coiinectingfwith said removable point, and means for. securingthe said landside for holding the landside and removable point` in position.

2. In a plow, a standard having a reduced point, a removable point positioned on said reduced point of said standard, a landside removably secured to said removable point jor holding the same in position, a bolt con-l nected with said standard for sliding said landside away :from the reduced pomt of said standard whereby tension is brought on said removable point for firmly holdin@r the same on the reduced point of said standard.

3. In a plow, a standardhaving a reduced point, a removable point adapted to engage said reduced point, said removable point being formed hollow for the purpos'eao surl roundin the said reduced point of the said standar ,'a' landside having an upstanding hook at one end, the said 'upstanding hookl .engaging with the said removable point, and

means for securing the said landside to said standard.

4. In a plow, a standard forme with a reduced point, a hollow l'remova le point adapted to fit oversaid reduced point of said standard, a landside 'formed withV a hook' shaped end, said hook-shaped end engaging with said hollow removable -point and clamping means arranged at the rear of said standard for clam ing4 said hook-sha ed end of the said landside to the said stan 'ard Where- Ybythel said removable point will 'be rigidly .held on said standard.

5. In a plow, a standard provided with a reduced point and a cavity formed in the -said hook-shaped end engaging the cross bar on the said removable point, and anadjustable securing member passing through said lug for clamping said lan hold said removable point rigidly on said reduced point of said standard.

` 6. In a plow, a standard provided with a reduced point, a removable point having a` cross bar positioned onits rear c nd, a landside mounted on the bottom of said standard and formed with a hook-shaped portion for engaging the said cross bar of said removable pointi and a screw bolt for causing tension to beexerted on said removable point and said landside whereby the said remov able point and said landside are made to rigidly engage the said standard.
